So been playing witch doctor, in act 3 hell now, trying to solo this shit and honestly it's tough, finding it hard to basically stay alive therefore unable to actual put out any damage, anybody got any build tips, and should I be using a shield to help with survivability? running with about 22k health and 4.1k dps, just wanna know some tips before I buy some upgrades or so!

What's your dodge, dr, and resistances? Yes, use a shield.

Level 56, 20k health, 108 all res, little more on light I think and I got dat 9k deeps

Would also love to hear some good advices..

Atm i am @ act1 hell lvl 55 and also having a very hard time..

ok, here is the build i use http://us.battle.net/d3/en/calculator/witch-doctor#fjUdRT!ZcU!cYZZaY

wat you wanna do is keep your gargantua on cooldown

then spirit walk into mobs, soul harvest and drop mass confusion

then spam the living shit out of zombie bears

with this build i had no problem on hell, and act 1 inferno

currently working my way through act 2 inferno, keeping the same build

oh and get more health, 20k is not that much at al
